X87: Remove kind field from StackHandler.

X87: Remove kind field from StackHandler.

port 15f8213809a57c2a163b500a732c9ffe5160a41a (r27263)

original commit message:

 This relands commit 96f79568a926966ebcf0685bf9adc947f4e1fbff.

 This makes the Isolate::Throw logic not depend on a prediction of
 whether an exception is caught or uncaught. Such a prediction is
 inherently undecidable because a finally block can decide between
 consuming or re-throwing an exception depending on arbitray control
 flow.

 There still is a conservative prediction mechanism in place that
 components like the debugger or tracing can use for reporting.

 With this change we can get rid of the StackHandler::kind field, a
 pre-requisite to do table-based lookups of exception handlers.
